indianatrekker64: Ratings generally track both the overall amount of viewers who tune in to a given program, and the amount of viewers of a specific target audience who tune in to a given program. Vegas scored high in overall viewership, but low in the specific target audience group (the demo/demographic) that CBS wants the show to appeal to. If it keeps getting high overall viewership numbers but a low score in the target demo, CBS is going to have to decide which set of numbers means more to them when it comes to deciding whether or not to renew the show.
